The corresponding structural topology optimization models are established respectively for the static problems and eigenvalue problems. At present, the research on engineering application of structural topology optimization is still immature, especially in China. In this paper, the structural topology optimization design theory is applied to the conceptual design of the actual engineering structure, and achieved better optimization results. Through the topological optimization of the classical example and the substructure of a satellite structure, it shows that the topology optimization model established in this paper can be effectively applied to the topological optimization design of engineering structure, which provides a valuable concept for structural type selection of engineering structure Design.
